No ace ask available

[Bbradley62]

I wanted to ask for aces over 2♥, but 4N was quantitative and 4♣ was a splinter.

( Deleted earlier response, when I misread the auction as starting with Jacoby not Stayman.)

 

In my part of the world, it IS a bit odd to not have 4C Gerber available after 1NT-2C-2H; many play 3S as an undisclosed splinter, 3NT by opener asks which suit.

With GIB, since you have direct splinter available in the minors available, you can bid 3♠ to set hearts as trumps, slam try, then bid 4nt later RKC. Over 2♠ you can bid 3♥ to set spades as trump.

 

GIB itself has issues with bidding 3♠ on some inappropriate hands (it should only be slam try hands, it too often does this on weaker stuff), but as human you have control.

I agree. Baze is what it is called here and it has 3oM as undisclosed splinter, 4♣ as keycard, and 4♦ as quant with a fit, and 4nt as quant without a fit (and hence 4 in the other major). Some people play modified Baze where the 4♣ and 4♦ are reversed in meaning (to allow a 4♦ last train counter try to 4♣ quant, I guess). There's a definite hole in system if 3-level bids imply no fit, and the only slam tries are natural splinters or quant.
